Bitcoin faces a derivatives event Friday, Aug. 28, as options contracts worth $6.44 billion expire on Deribit at 08:00 UTC.

The expiry involves 81,700 Bitcoin options: 44,639 calls and 37,061 puts, according to Deribit Metrics. The 0.83 put-to-call ratio shows bullish bias—calls outnumber puts, meaning traders are positioning for upside.

Max pain for the expiry sits at $69,000, the strike where the most contracts expire worthless and inflict maximum losses on option buyers. That level coincides with Bitcoin's 200-day moving average, a technical flashpoint Frank Hepworth, founder and CEO of New Market Trading, flagged as critical.

Call concentration stacks higher: the $75,000 strike holds $236 million in notional open interest, followed by $80,000 with $157 million. That positioning reflects expectations for Bitcoin to trade higher.

Hepworth noted that 62 percent of this Friday's expiring contracts are already worthless, and expiry weeks often "sound scarier than they are." He expects a market pullback this week but sees the $65,000–$69,000 range as a bullish signal if Bitcoin holds it—confirmation that the bear market low is in the rearview.

September's options expiry is nearly double the size of August's event. The Crypto Fear & Greed Index registers 71, in "Greed" territory, reflecting the bullish sentiment baked into current positioning.
